Raymond Sewage Lagoon - Secondary Wastewater Treatment in County of Warner, Alberta

Raymond sewage lagoon is a wastewater treatment facility located in the County of Warner, Alberta, Canada. The plant provides secondary treatment for municipal wastewater, serving the local population in this rural region of southern Alberta. As a secondary treatment facility, Raymond sewage lagoon meets the standard level of treatment required for municipal wastewater in Canada. Under the Canadian Council of Ministers of the Environment (CCME) guidelines, secondary treatment is the baseline for protecting receiving water quality. The plant operates under provincial regulations administered by Alberta Environment and Parks. The treated effluent from Raymond sewage lagoon is discharged into the local watershed, which ultimately drains into the Oldman River system, a tributary of the South Saskatchewan River. This river network flows through the prairies and supports agricultural irrigation, aquatic habitats, and downstream communities before reaching Lake Diefenbaker and eventually Hudson Bay.

The Raymond sewage lagoon discharges into the Oldman River watershed, part of the South Saskatchewan River Basin. This semi-arid region relies heavily on the river for irrigation and municipal water supply. The downstream environment supports diverse aquatic life, including fish species such as walleye and northern pike, and provides critical habitat for migratory birds along the Central Flyway.
